swev-id: pytest-dev__pytest-7490

[casey-brooks]

Summary

• re-evaluate xfail markers during call so dynamic markers update reporting
• ensure run=False xfails skip execution without duplicate reporting and add regression coverage
• update pre-commit hooks to fetch flake8 from GitHub and pin black's click dependency for reproducible linting

Testing

• PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 .venv/bin/pytest testing/test_dynamic_xfail.py testing/test_skipping.py
• . .venv/bin/activate && tox -e linting
• tox -e py38 (fails: setuptools vendored typeguard plugin still declares addini type="string" and trips pytest's assertion; unrelated to this patch)

Resolves #33.
